Construction Zone and Highway Accidents: Who Is Liable?

Construction zones can be some of the most dangerous stretches of road in Ontario. Sudden stops, lane changes, narrow roads, reduced speed limits, shifting traffic patterns, and workers on foot can make driving through these areas more challenging and increase the risk of a motor vehicle accident.

While construction projects are essential for maintaining and improving Ontario’s transportation system, accidents can still occur when drivers, contractors, traffic control companies, or government bodies fail to meet their responsibilities.

When a crash occurs in a construction zone, determining who is liable can extend beyond the drivers involved. Depending on the circumstances, responsibility for an accident may rest with one or more parties.

Who Can Be Liable for a Construction Zone Accident in Ontario?

The Driver or Drivers Involved

Drivers have a responsibility to adjust their driving to the conditions of a construction zone. This includes slowing down, paying close attention to changing traffic patterns, following posted signs, and merging safely.

Speeding, distracted driving, failing to obey construction signage, or improperly merging may result in liability being placed on the driver who caused the collision.

However, the fact that a driver was involved in a construction zone accident does not necessarily mean they are solely responsible. Other parties may also have contributed to the conditions that caused the crash.

The Construction Company

Construction companies have a responsibility to take reasonable steps to maintain a safe work zone for both workers and motorists.

A construction company may potentially be liable when unsafe conditions contribute to an accident. Examples can include:

• Missing, inadequate, or unclear signage
• Improperly positioned barriers or barricades
• Debris left in a travel lane
• Poor lighting or visibility at night
• Unsafe changes to traffic patterns
• Failure to properly maintain the construction area

Construction contractors owe a duty of care to motorists travelling through the work zone and are expected to take reasonable measures to provide a safe driving environment.

Traffic Control Subcontractors

Many construction projects involve a separate company responsible for traffic control. These companies may be hired to install and maintain cones, signs, barricades, and other traffic control measures or to provide flaggers and manage traffic around the construction site.

If a traffic control subcontractor fails to establish or maintain an adequate traffic control system and that failure contributes to an accident, the subcontractor may potentially be held responsible for the resulting injuries and losses.

The Municipality or Ministry of Transportation (MTO)

Government bodies, including municipalities and the Ministry of Transportation (MTO), may also have potential liability in certain construction zone accidents.

Depending on the circumstances, a municipality or the MTO may be responsible if it:

• Approved an unsafe traffic control plan
• Failed to properly oversee a contractor
• Failed to address a known hazard
• Failed to take reasonable steps to maintain roadway safety

Because construction projects can involve multiple parties, responsibility for an accident may be shared between a driver, construction company, traffic control subcontractor, municipality, or the MTO.

How Does the Occupiers’ Liability Act Apply to Construction Zone Accidents?

Under Ontario’s Occupiers’ Liability Act, an occupier of a property has a duty to take reasonable care to ensure people using the premises are reasonably safe in the circumstances.

In the context of a construction zone or roadway, liability may arise when a contractor, subcontractor, municipality, or other responsible party fails to address a dangerous condition.

For example, an injured person may have grounds to pursue a claim when a responsible party:

• Failed to provide appropriate warning signs
• Left hazardous materials or debris on the roadway
• Created an unsafe traffic condition
• Failed to address a known hazard
• Otherwise acted, or failed to act, in a way that contributed to the accident

Determining whether the Occupiers’ Liability Act applies to a particular accident depends on the circumstances and the parties involved.

Notice Period for Claims Against a Municipality

One of the most important issues following a construction zone accident is determining whether a municipality may be responsible. Claims against municipalities can involve strict notice requirements that injured people need to understand.

Under the Municipal Act, a person may generally be required to provide written notice of a claim against a municipality within 10 days of the accident. Failing to provide notice within the required period can potentially affect the ability to pursue a claim.

There are exceptions to the notice requirement in certain circumstances, so missing the 10-day period does not necessarily mean a claim is automatically lost. However, because these deadlines can have serious consequences, it is important to seek legal advice as soon as possible after an accident.

This is one of the reasons you should speak with an Ontario personal injury lawyer promptly after a construction zone accident rather than waiting until your vehicle is repaired or your injuries have healed.

What Should You Do After a Construction Zone Accident?

If you have been injured in a construction zone or highway accident, identifying the responsible party may not be straightforward. Multiple parties could potentially share liability, and important evidence may need to be preserved.

Seeking legal advice early can help determine:

• Who was responsible for the construction zone
• Whether a traffic control company was involved
• Whether a municipality or the MTO may have liability
• Whether unsafe road conditions contributed to the accident
• What notice and limitation periods may apply
• What compensation may be available for your injuries and losses
